[sdiy] Random Tone Generator redux

[Ian Smith]

Hi all,

Here's a link to a schematic that I drew up for that pseudo-random tone generator.

http://www.sdiy.org/modius13/randtonereduxschem.pdf

If there's anything anyone can think of to add to it feature-wise that would make it a decent module, I'm open to suggestions. (trigger outputs, different waveforms, multiple voices in one package, etc.)

Thanks again,

-Ian
